Gravitation is a scientific term that refers to the force that attracts objects with mass to each other. This force is what keeps the planets in our solar system in orbit around the sun, and what keeps us on the Earth's surface. When we talk about gravitation, we are usually talking about the relationship between objects with mass and the way they interact with each other. It's a very important concept in physics and astronomy. In everyday language, we might use the word gravity to talk about the same idea.
